    Abstract: An absorbent article comprising a central absorbent member and a lateral wicking barrier for inhibition of wicking from the central regions of the article to an outlying outer absorbent member. The wicking barrier has a vertical component for prevention of radial wicking in the plane of the article and thus promotes center filling of the article with fluid and reduces the likelihood of leaks from the sides of the article. The wicking barrier can also have a horizontal component to prevent leakage, redirect fluid flow, and improve fit and performance of the article. In one embodiment, the central absorbent member is a concentric absorbent structure having alternating rings of barrier material and absorbent material, including a spiral wound composite formed from a layer of barrier material wound with a layer of absorbent material and then sliced to provide a thin absorbent layer having high permeability in the thickness direction but low permeability in the plane due to the barrier material. In a second embodiment the absorbent Core consists out of an outer absorbent member having a central void, open toward the body side of the absorbent article a central absorbent member disposed over and extending into the open void and a wicking barrier disposed between the outer and central absorbent member.

    Abstract translation: 一种吸收制品，其包括中心吸收体和侧向芯吸屏障，用于抑制从制品的中心区域排出到外面的外部吸湿件。 芯吸屏障具有用于防止制品平面中的径向芯吸的垂直部件，从而促进制品与流体的中心填充并减少从制品的侧面泄漏的可能性。 芯吸屏障还可以具有水平部件以防止泄漏，重定向流体流动并改善制品的配合和性能。 在一个实施例中，中心吸收构件是具有阻挡材料和吸收材料的交替环的同心吸收结构，包括由缠绕有吸收材料层的阻挡材料层形成的螺旋缠绕复合材料，然后切片以提供薄的吸收剂 层在厚度方向上具有高渗透性，但由于阻挡材料在平面中具有低渗透性。 在第二实施例中，吸收芯由具有中心空隙的外部吸收构件组成，朝向吸收制品的身体侧开放，设置在开放空隙中并延伸到开放空隙中的中心吸收构件和设置在外部和中部之间的芯吸屏障 吸收体。
